Recently, climate change and human activities accelerate hazards, such as deforestations, land slides, draughts, floods in Asian-Pacific countries are increased. To mitigate the hazards due to climate change and human activities, environmental monitoring has become important. Environment change monitoring by using space based technology are very important. Asian Pacific regional forum (APRSAF) agreed to host SAFE (Space Applications For Environment) initiatives. Under APRSAF, there are on-going several SAFE prototyping for water management, agriculture, fishery and coastal monitoring This paper describes SAFE overview and current situation of SAFE prototyping.
We present a generating method of stereoscopic images from moving pictures captured by a single high-definition
television camera mounted on the Japanese lunar orbiter Kaguya (Selenological and Engineering Explorer, SELENE).
Since objects in the moving pictures look as if they are moving vertically, vertical disparity is caused by
the time offset of the sequence. This vertical disparity is converted into horizontal disparity by rotating the images
by 90 degrees. We can create stereoscopic images using the rotated images as the images for a left and right
eyes. However, this causes spatial distortion resulting from the
axi-asymmetrical positions of the corresponding
left and right cameras. We reduced this by adding a depth map that was obtained by assuming that the lunar
surface was spherical. We confirmed that we could provide more acceptable views of the Moon by using the
correction method.
